The Mechanical Handling and Storing of Material

COKE FROM COKE OVENS 375 to enable the rail track to be laid on a higher level. The coke can be delivered into a bunker and raised by a bucket elevator to the screen. The Burnett machine is simple, but requires plenty of room which is not always available in old cokeries. The Méguin loader for coke (Fig. 527) was built for a Belgian cokery, and consists Fig. 527. The Méguin Loader. of a portable contrivance having a screen connected with an inclined plate conveyor a, with angle-iron sides. It delivers the coke to a bar screen b, provided with a balanced swing extension c, enabling the coke to be loaded into any desired truck. The screenings fall into a bunker d with a discharge slide the conveyor is driven by a belt from shaft/, and the travelling motion of the whole carriage is transmitted by chain g. Fig. 528. Portable Loading Device of Allport. As the illustration shows, the Méguin loader runs on a rail track parallel with the ramp, and between it and the siding for the coke trucks; the ramp is sufficiently steep for the coke to slide down readily. There is a tendency to make the hearth or tamp still shorter and steeper so as to use it simply as a means of conveying by gravity, instead of its original purpose, i.e., for cooling, and we shall see that in some instances the
